Love is not narcissistic or egocentric. Infact, love is respect, it is compromission, understanding, patience and acceptance. If you find yourself in a situation where your partner doesn't serve give any of these then it is not love.
Have you ever thought of skipping today without calling him? Not actually being the first to apologize during an argument this time around? Would he call you when he notices you haven't? Will she put her pride down and apologize if you didn't? Will he or she walk away because you told them the things they so that hurt you? If the answer to any of these is NO! Then be rest assured the other person is not in love with you.
What about situations where the other person doesn't care about your growth, your happiness or discomfort themselves sometimes just to see a smile on your face? Or do things before your very eye that would hurt you? Or even situations where she makes you her money bag and never give even a little gift to you or he only decides to love you behind closed doors, during sex and keeps you as his dirty little secret? That is simply not love.
Perhaps at this point you should walk away, give them the time to decide if it's you they really want and give yourself time to think if you really want to be treated that way. We would all advice a loved one to walk away if they ever fall into any of these but most times find it hard to walk out when we are in this very situation.
And most times we forget the emotional and psychological torture that comes with choosing to love a person who I'll treats us. It's okay to walk away when you don't get the kind of love you deserve, it's their loss and not yours. How are you ever going to be with someone who treats you better if you don't let go off someone who doesn't? It may seem hard, even the thought of living without them scared you but you'll be glad you did.
